Bubugao vivo X1 is a very popular Android phone recently. It doesn't compete for configuration and price like ordinary Android phones, but it has an unusual Pinyin quality. It is also the first mobile phone that has really entered the door of Hi Fi. It uses CD player level DAC chips Cirrus Logic CS4398 and CS8422 as SRC chips, which are rarely seen in mobile phones. Of course, we know that to study the sound quality, the "core only theory" is not desirable, and the sound quality still needs to be tested on a real machine to know how powerful it is. Let's follow the author into X1's music world.
The front shape of vivo X1 is similar to that of ordinary Android phones, but it is thinner than all phones, with a thickness of only 6.55mm. We also compare MOTO Razr and OPPO Finder, two other "blade" phones, to see who is more "sharp".
In the side contrast, Razr is not so coordinated because of the whole protrusion of the camera, while the Finder camera is also very protrusion, while X1 has a completely flat back and the smallest thickness.
Of course, too thin also causes some minor problems. For example, the headphone plug here is too large, which makes the whole phone stand up.
Returning to the theme of our test - sound quality, we selected more devices in this test. The iPhone 5 is recognized as a better phone for comparison, and the MMX 71 iE with X1 original, earpods with iPhone 5 original, VC02 with Vsonic, UM1 and UE10 with Westone as earphones.
Test song format: AIFF and MP3 are used for iPhone 5, and FLAC and MP3 are used for X1.

X1, as a rare mobile phone that plays the "sound quality card", will certainly have something outstanding in the music playing function.
X1's playback interface is cool and fashionable, with a dynamic album cover display in the middle.
After clicking the position of the album cover, options such as progress bar, sound effect selection, loop and random play will appear.
X1 has a wide range of sound effect options, of which the biggest highlight is of course the Hi Fi mode. After this option is enabled, digital to analog conversion will be carried out through CS4398. In order to maximize the strength of X1, the following test is based on the Hi Fi mode.
BBE sound effect. After being turned on, human voice and dental sound increase. Low frequency is unnatural, so it is not turned on in the test.
SRS sound effect, very heavy taste, too much low-frequency rendering.
iPhone 5
The playback interface of iPhone 5 is quite similar to that of X1, but the difference is that the sound effect options are in the system settings, and there are many built-in sound effects, but the sound effect is not good when turned on.
Sound quality comparison (the following comparison X1 selects Hi Fi mode without turning on any sound effect, and iPhone 5 adopts the default setting)
high frequency : The high frequency of X1 is more textured than that of iPhone 5, and the high frequency of iPhone 5 seems dry. The high-frequency of X1 is more gorgeous than that of iPhone 5, but the high-frequency extension still needs to be improved.
intermediate frequency : In terms of IF, X1 is thicker than iPhone 5, and the voice is more emotional. From the perspective of tuning, it can be said that X1 is more flavorful, while iPhone 5 is relatively lacking in emotion.
Low frequency : X1 feels a little soft at low frequency. Although it can guarantee a good low frequency, it always feels that the low frequency is not enough. The low frequency of iPhone 5 is relatively small, but it is more clear than X1 in low frequency and can dive deeper. In terms of dynamic performance, X1 is better than iPhone 5.
analysis : X1 is better than iPhone 5 in sound resolution and has more information. However, due to the relatively thick and strong dynamics of the IF, it gives an illusion that the resolution is not as good as that of the iPhone 5.
sound field : The horizontal sound field of X1 is wider than that of iPhone 5, and with its sharp dynamics, it gives a more three-dimensional feeling. But the iPhone 5 performs better in the longitudinal sound field.
On the whole, X1's quality is higher than that of iPhone 5. Of course, this result is also expected by the author. The overall sound of X1 follows the high fidelity line, but has added many unique tuning styles It is believed that the engineers who step by step have also made great efforts in this aspect. However, there is still a gap between the traditional Hi Fi Walkman and the mobile phone. Of course, our requirements for a mobile phone cannot be so strict. For Android phones, the sound quality of X1 is definitely a milestone, and it is not a problem to challenge iPhone 5. X1's hardware quality is very excellent. Next, we should do a good job in tuning, especially in bass diving, so that its comprehensive performance will be better.
X1 is suitable for the crowd: users who want to carry high-quality voice, but do not want to buy a walkman.
